在Python虚拟环境中使用环境外的mysql

环境：win8 64bit、Python2.7、mysql 5.6.20，

Python和mysql连接使用MySQL-python-1.2.3.win32-py2.7

描述：

我是下载MySQL-python-1.2.3.win32-py2.7.exe后双击打开运行安装，安装正确，可以在cmd命令行正确启动数据库。但是我需要在virtualenv环境下使用mysql，问题出现了：

由于安装MySQL-python-1.2.3.win32-py2.7是下载后双击打开安装的，也就是说在虚拟环境外部安装的，所以在venv环境中import MySQLdb时提示没又该模块。但是又要在虚拟环境中使用，请各位老师指点一番，谢谢

1：在虚拟环境中如何安装MySQL-python-1.2.3.win32-py2.7

2：在虚拟环境中是否能够引入环境外的包

终于找到方法了，马上哭出来了。。。。。
pip install --allow-external mysql-connector-python mysql-connector-python
要写两遍，难道是重要的工具要写两遍。。。。
测试成功

虚拟环境中选择源码来python setup.py install安装。

网上搜的下述方法也是不对

 > pip install mysql-connector-python
You are using pip version 7.0.3, however version 7.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

如果你可以安装mysql-python globally (in C:/python27) （ http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python）。你把你的python目录lib/site-package

• MySQL_python-1.2.4-py2.7.egg-info(folder)
• MySQLdb(folder)
• _mysql_exceptions.py/.pyc/.pyo
• _mysql.pyd、

这四个文件复制到你的虚拟环境的site-packages目录下，就可以使用了

搞了一下午终于好了，感谢楼主
